Memory Testing -- Windows 2003 Server ?

I am getting ready to upgrade to 2012 server,
but want to first fix my "the instruction at
.... referenced memory at ..... the memory
could not be read" ERROR on my
Dell PowerEdge 2950.

What tests do you recommend so I can
determine if the motherboard, memory,
hard-drive due to VirtualMemory,
or something else needs fixing ?
============================================
Possible Tests

 1. Dell Diagnostics PSA/ePSA
      ** run outside of Windows since you
         can't reliably test the RAM
         while the OS is running

 2. https://technet.microsoft.com/en-us/magazine/2008.09.utilityspotlight.aspx
      ** Windows Memory Diagnostic

 3. http://www.memtest86.com
      ** three perfect passes

 4. http://www.memtest.org

 5. etc ?

memtest86 with multiple passes = your mem is good.
You need not test further.

Agree with the above.

In every case where I have seen the cited error, it was a software problem.

Various possibles here:

Bad memory
Virus infection
Memory not seated correctly (remove, blow out slots, wipe sticks with tissue paper to remove dust, reseat in slots)
Dust on memory sticks (use method in line above)

If you've tested the memory then try the next three possible causes.

take out each stick, clean the contacts, - also the contact slots on  board and install it in a different slot
then run memtest86+ again :  www.memtest.org

it is also wise to run a diagnostic on the disk(s) - i use the ubcd for this :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

**  you can make a bootable cd - or bootable usb stick

****if all disks are ok, --> now run a chkdsk on your drives!

Various software bugs give this error, faulty RAM does *not* give this error. Faulty RAM gives either a silent ECC corrected error recorder on the baseboard management controller log or an NMI parity check that crashes the server.
